Install

You need python3, mysql-server, rabbitmq-server and redis-server to be installed.

Create python virtual env and activate it in your favorite way.

Clone project

git clone git@github.com:OnGridSystems/CATEd.git

Go to project dir

cd CATEd

Create mysql databases

echo "create database trade character set utf8; create database celery_result; create database portal_ticker;" | mysql -u root

And migrate

python manage.py migrate

Load initial data with some exchanges and wallets

python manage.py loaddata dump.json

Create you own superuser with

python manage.py createsuperuser

Before starting the bot should read the list of currencies from the site coinmarketcup.com. To do this run following code with activated virtual environment.

read -d "" PYTASKS <<"EOF"
from tradeBOT import tasks
coinmarketcup = tasks.pull_coinmarketcup()
EOF
echo "$PYTASKS" | python manage.py shell

And runserver

python manage.py runserver

Now you can add your api keys.

Add NEW api keys for use bot.

To do this open http://127.0.0.1:8000/ in your browser, login and click red "plus" button in the lower right corner.

Bot uses several celery queues for trade, and main is triggered by a signal from a first worker named celery@worker_high. Another worker - worker_set_orders checks for already existing orders and try keeps them up to date. There are also queues low and normal, for calculating users' orders and pulling their balances.

You can run celery in several terminal windows or screen sessions:

celery worker -A djangoTrade -n worker_high -l info -c 1 -Q high
celery worker -A djangoTrade -n worker_set_orders -l info -c 1 -Q set_orders
celery worker -A djangoTrade -n worker_low -l info -c 2 -Q low
celery worker -A djangoTrade -n worker_normal -l info -c 2 -Q normal

Example of running celery with supervisor daemon:

wget https://raw.githubusercontent.com/celery/celery/4.0/extra/generic-init.d/celeryd -O /etc/init.d/celeryd
wget https://raw.githubusercontent.com/celery/celery/4.0/extra/generic-init.d/celerybeat -O /etc/init.d/celerybeat
chmod +x /etc/init.d/celeryd /etc/init.d/celerybeat
